The length of a cell phone is 1, point, 21.2 inches and the width is 4, point, 84.8 inches. The company making the cell phone wants to make a new version whose length will be 1, point, 6, 81.68 inches. Assuming the side lengths in the new phone are proportional to the old phone, what will be the width of the new phone?
To find the width of the new phone, we need to use the fact that the side lengths are proportional.
First, we can find the ratio of the length of the new phone to the length of the old phone:
length ratio = new length / old length = 1.68168 / 1.212 = 1.3846
Next, we can use this ratio to find the width of the new phone:
new width = old width * length ratio = 4.848 * 1.3846 = 6.714688
Therefore, the width of the new phone will be approximately 6.71 inches.
